INXE and LRTE: Progress on Frequency Standards and Timescales

Abstract

In this work, we overview some progresses of the Brazilian scientific program for time and frequency metrology. The results involve the development of an atomic fountain of Cs 133, a compact frequency standard with cold atoms and two new timescales contributing to TAI and UTC. These are different running experiments in two locations in Brazil and consists on a joint effort to develop infrastructure in the area.
